Explain why the rim brakes on a bicycle wheel are located at the outer edge of the
Question:
Explain why the rim brakes on a bicycle wheel are located at the outer edge of the wheel instead of near the hub. Consider the work–energy theorem (Eq. 9.9) and how the magnitude of the torque produced by a given force varies when the force is applied at different distances from the axis of rotation.
Step by Step Answer:
The workenergy theorem states that the work required to stop the wheels equals the applied torque multiplied by the angular displacement Therefore the larger the torque applied to the wheels the shorter the stopping distance of a bike For a given force the largest torque comes from placing the force as far away from the center of the wheel ...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
